PATENT OFFICE- LOG-LOADER.

SPECIFICATION forming part of Letters Patent No.. 768,402, dated August 23, 1904.

Application filed November 3,1903. Serial No. 179,715. (No model.)

To all whom, it may concern:

Be it known that I, OSCAR L. RAYMOND, a citizen of the United States, residing atIBallentine, in the county of Ontonagon and State of Michigan,-have invented a new and useful Improvement in Log-Loaders, of which the following is a specification.

My invention relates to a device for loading logs on sleds and is adapted to be transported on runners from place to place.

The object of my invention is a portable logging-derrick by means of which logs may be picked up from'either side of the sled on which they are to be loaded and placedin position on either the near or far side of said sled.

My invention consists in the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings. in which Flgure 1 is a perspective view of my improved derrick or log-loader. Fig.2 1s a perspective view showing the loader in operation,

- rotatable, and to them are secured the poles B, adapted to be lifted into a vertical position, as shown in Fig. 1. These poles are at opposite ends of the device when the sleds are arranged tandem, so that the device may be drawn from either end, and it is not, therefore, necessary that it be turned around in order to move it from place to place.

Mounted on the sleds is a frame C, which frame comprises the side pieces C, an end piece C a narrow platform C at the opposite end, and the under cross-pieces C*, a cross-piece C resting on each of the crosspieces A A king-bolt A pivotally connects the frame C to each of the sleds, the bolts passing through the cross-pieces-A and C, the upper ends of the bolts projecting upward through a central longitudinal beam C venting rear movement of the sled.

and being perforated and held in place by a suitable key. By removing the key the bolts will drop out of place and the frame C may be readily removed from the sleds.

Arranged on the platform C is a derrickstandard D, reduced in its upper portion, a shoulder D being formed at the lower end of the reduced portion. A swing-boom E is enlarged at its inner end and recessed to fit around the reduced portion, as shown'at E in Fig. 3, the inner end. of the boom bearing on the shoulder D. The boom tapers toward its free outer end and reduced at the end and "also perforated adjacent the reduced end.

The standard D is braced by the brace-rods F, which bear at their lower ends on the side pieces C.' To theseside pieces are pivoted adjacent the .platformC which is at the forward end, ends of brace-bars Cr, the free ends of these bars resting on the ground and prle- Tie standard D is further braced and held rigid by suitable fixed guy-ropes H, and guy-ropes H are also provided, by means of which the standard can be braced from. either side by securing the ends of the ropes H to stumps or trees, as shown in Fig. 2.

Connected to the free end of the boom is a block and tackle J, arranged in the usual manner, a pair of chains J, having hooks at their free ends, being carried. by the lower block. The boomis braced by a'cable K, connected at one end to the upper end of the standard D and having its lower forward end connected to the reduced portion ofthe boom, the cablefirst passing through the perfora tion, so that it is prevented from slipping off the reduced end of the boom. The lower portion of the standard is slotted, and a pulley L is arranged in the slot, and a block and pulley L is arranged just under the boom adjacent its juncture with the standard. A cable M, forming a part of the tackle J, runs over the pulleys L and L in the order named through an eye or staple N on the end piece C and is connected tothc pole B at that end of the device. g

Suitable trees are pivotally connected to the pole, so that the device may be operated by horsepower, though, if desired, steampower may be used and the cable M wound on a drum in the usual manner. A rope O is attached to the boom, by which it is swung to the proper position over the logging-sled, and a rope O is attached to the lower block of the tackleJ, so that the chains may be drawn back after a log has been placed in position. When the device is being moved from place to place, the crotch-chains J may be attached one to each of the front corners of the frame C, so as to prevent the boom from swinging from side to side. The two sleds used are also preferably connected by means of two chains P intersecting each other, as shown in Fig. 1.

In use the device may either remain on the sleds, as in Fig. 1, or it may be dismounted, as shown in Fig. 2, and the sleds used for the logs. When in operation, a man stands on the side opposite the skidway and by means of the rope 0 draws the boom to the proper position to place the log'on the sled, and the log can be dropped either on the longitudinal center of the sled on the side nearest the skidway or it may be lifted over logs already on that side of the sled and lowered into position on the side farthest from the skidway. When the log has been dropped into position and the hooks have been detached from the ends of the log, the chain J, and with it the boom E, is drawn back over the skidway by means of the rope 0.

It will be noted that this device is simple in construction, with but few parts and all of ard, a block and tackle carried by the boom, chains having hooks at their ends carried by the lower block, a pulley arranged adjacent the juncture of the boom and the standard, and a portion of said tackle running over the last-mentioned pulley and rearward over the pulley arranged in the slotted portion of the standard 2. A device of the kind described comprising two sleds, said sleds comprising crosspieces, rods connecting the ends of the runners, poles secured to a rod on each sled said poles extending in opposite directions, a frame having under cross-pieces resting on the crosspieces of the sleds, a longitudinal beam carried by the frame, and king-bolts passing through the cross-pieces of the sleds and frame and through the longitudinal beam, means for holding said bolts in place, a derrick-stainlard supported by the frame, and means carried by said standard adapted to lift logs.

3. A device of the kind described comprisingsleds arranged tandem, a. rectangular frame removably arranged on the said sleds and serring to connect the sleds, a platform on the forward portion of the said frame, a standard mounted on the platform, said standard being reduced in its upper portion and having a shoulder formed at the lower end of the reduced portion, a boom having a recess formed at its rear end adapted to lit over the reduced portion of the standard and to turn on same, the said boom bearing on the shoulder carried by the standard, the boom being reduced adjacent itsfree end, a bracing-cable secured to the upper end of the standard and to the reduced portion of the boom, a block and tackle carried by the boom, crotch-chains carried by the tackle, means for swinging the boom horizontally, and means for bracing the standard, substantially as described, and. for the purpose set forth.
